West Ham joint-chairman David Sullivan says Javier Hernandez could be one of the greatest players to have ever signed for the club.

He becomes the 33rd striker signed by the club since Sullivan and David Gold took over. But Sullivan believes they have struck gold with £16million “Chicharito” (or “Little Pea”), from Bayer Leverkusen, which will delight Slaven Bilic .

“He is potentially the best player to ever come to the club,” said Sullivan.

“He is probably the best proven goalscorer we have signed. He’s done it in the Premier League with Manchester United. His goalscoring was a goal every two-and-a-half games, so that’s a pretty good record.”

Sullivan also refused to rule out a move for England and Arsenal star Jack Wilshere, among others in August.

The Hammers chief added: “I can’t comment on players from other clubs and we have a lot of good midfielders at the club, but never say never."
